Yes, now that I think of it, there is one of these "crazy" joins
that's probably coming into play that joins each of my 7000 rows
with 65 rows in a different table, so that table must have about
450,000 rows. Any good optimization approaches for these type of
one to "very many" relationships? recursive fetch? I can see this
table getting into the many millions of rows real fast.
I'd spend some quality time considering a different design. I doubt
it is doing a crazy join. My money would be on Mike's prediction of
insane amounts of rapidly scrolling SQL. ERXBatchFetching can be a
big help here, properly used.

Either some crazy joins with other tables or something you are not

hmm, I'm not doing an insert at all, just a read. Kind of thought
there must be something else too though (with my limited experience)
but figured indexing would be a good thing to do regardless before
digging into debugging the real culprit here.

More than a minute to insert to a 7000 row table?
Do other operations on the same DB take an appropriate amount of
time? If not I would start looking at DNS or other connectivity
issues. I can't fathom a FB DB sucking at that level.
this was my first thought, too ... something else is going on
here. I suspect if sql debug was turned on, you'd see tons of
faulting going on that you didn't realize and that the insert
itself is not actually the slow thing.
